# Introduction

**Current Version: 2.1**

Welcome to the RealTrex API. This service provides access to broker price opinions through specialized endpoints. All endpoints target `api.realtrex.com`.

## API Versioning

The RealTrex API follows semantic versioning to ensure stability and backward compatibility for our clients:

### Minor Releases (Non-Breaking Changes)

Minor version updates (e.g., 1.8, 1.9, 2.1) **only add new functionality** and do not remove existing features within the same major version. These updates are designed to be fully backward compatible, meaning your existing integrations will continue to work without any changes.

### Major Releases (Breaking Changes)

When a major version update is released (e.g., 2.0), it may include breaking changes such as removed or significantly modified endpoints. However, we ensure continuity by:

* Keeping the previous major version available and supported for an extended period
* Providing complete documentation for the previous major version
* Giving advance notice before any major version changes

This approach ensures your applications remain stable and functional, regardless of which API version you're using.
